To all whom it may concern.:

13e it known that l1, Josiiiii C. DAY, of Hackettstown, in the county of\\'arren and State of New Jersey, have invented certain new and usefulImprovements in Fire-Arms, and I do hereby declare that the following isa full and clear description thereof, reference beingr had to theannexed drawings, in which- Figiire 1 is a side view of the gun; Fig. 2,alongitudinal section through stock and barrel; Fig. 3, a plan view;Fig, et, a side view of the rear portion of the barrel; Fig. 5, aplanvicw ofthe saine; Fig. (3, a transverse section in line 1 1 of Fig.2; Fig. 7, an end View of the rear end of the barrel; Fig. 8, alongitudinal section through the gun, showing -the barrel in position toreceive lthe charge; Fig. .9, a perspective view -oi' the trigger,worliing the loose'collar l), Fig. 1l), an elevation ofthe lock, thehammer being at full-cock; Fig. 1l, a longitudinal sectionA of the ea]i-1`eediiig tube, Fig. 12, a transverse section olf the same, Fig. 13, aperspective view of the follower s,- Fig. 1J., an end View of the loosecollar D, Fig. 15, a top view of the saine; Fig. 1li, aniodified forniofthe shank of the loose collar 1l); Fig. 17,' a perspective View ofthis modified form with the trigger a. inserted; Fig. 1S, :i iiiodii'iedway of locking the barrel; Fig. iti, :i section ol a ball before theexplosion ol' lthe powder has affected it; Fig. 2U, a section of thesame after the explosion. l A

My invention relates, iirst, to a manner of arranging the two side'pieces between which the barrel is liiiii different from that describedin niy former `.i-ttersliiteiit; second, 4to a different construction ofthe sliding collar which holds the barrel in its position when the gunis to be discharged.

'lo enable those skilled in t-he art to make and use iiiy invention, lwill proceed to describe its construct-ion and operation.

thang the barrel A, ip the saine manner as described iii my Lettersl?ateiili, between two side pieces, laiid l?. i3 is east together with amalleable cast -iron ease, l, which forms 'the noch of the stock, and B2is jointed to ll by hinge l. rEhe side piece ll".is provided with aprojection l at its rear end, which is made to fit closely iii acorresponding recess in Gasen. A Screw, ai, 'fasteiis it firmly to thisl ease. By this arrangement I am enabled to shown in Fig'. 18.

remove th'e barrel with the least loss of time by unserewiiig screw cand turning over side piece l-l'l.

The sliding collar l),wliich serves to tix the rear end of the barrel tothebreech (l and to close the lioiiit, instead of providing it with twoknobs, as specified in my 'former Letters latent, I arrange with a stem,l), and a trigger, a, which straddles in the shape of `a fork over thisstein and catches iii the-two notches 1) D3. A spring, I), is placed soas to press against this trigger c, whose fulcrum is in a cavity, a', ofthe ease 13, and Aforces thereby the sliding collar D up to the rear endof the barrel. rlhe stationary breech G, upon which collar l) rides, ismade round, and the face of it in the shape ot' an are, as specified 'inmy former Letters latent, but there is a groove, C,tiiriied out ol' itssiirface,which leaves only a narrow cylindrical place at the edge of the1 breech C for the sliding collar D to ride upon.

rlhe projecting piece A of the iear end ofthe barrel A is made similarto this breech. It is `left cylindrical for a short distance atits edge,

and provided -with a groove, A2. rlhese grooves Gand A, I nialc for thepurpose of providing a place where the fouling may 'collect, and todecrease the surface upon which the sliding collar D moves, therebylessening the friction and securing a free and easy niotion of thesliding collar.l The face of this collar is made on the same sweep asthe rear end of the barrel A, and its outer edge sharp, so as to presenta cutting-edge to the rear of the barrel A. 1f, then, the cartridge isinserted in the chamber A'2 and barrel forced back to the position shownin Figs. 1 and 2,I the edge of the collar will cut off the rear end ofthe cartridge, and thereby open a passage into the powder, whichoperation lis clearly shown iii Fig. S. l

A modified plan of locking the barrel is The barrel A ishung be-l tweentl ie sides in the saine manner; but the rear end ol" the barrel,insteadof being in the shape of an are, is made straight, not square with thesides, but. somewhat inclined, and the face of the breechof acorresponding inclination; or it may be made` of circular forni similartothe first arrangement, so that both l'orin a tight joint when thebarrel is brought down.. The inclination of the joint must be l hinge,B3, and locking them by the projection of such an angle that the lowercorners of the` barrel in loeing` raised would clear the breech, but notlarger. A knife, u, inserted into a recess in the top of the breech witha spring, @,behind it would perform the shearing operation to remove therear end of the cartridge. A triggenVV, of hook-like shape, catches in anotch at Ythe lower side of the barrel and holds the barrel locked.

"What I claim as my invention, and desire to secure by Letters Patent,in addition to my former claims, is-

l. Connecting the two side pieces, B and 1, between which the barrel ishung, by a B", and a corresponding recess, substantially as set forth.

2. Making the faceof the sliding collar D of the shape of an arc, with aycutting-edge, so as to act in combination with the rear endv of thebarrel as shears for the purpose of removing the rear end of thecartridge, as described. 3. The groove C and A2 in the breech vand therear end of the barrel, for the purpose set forth. e JOSEPH. G. DAY.Vitnesscs:
